Description

The SN74LVT16244B devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) V _CC operation, but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE) inputs.
When V _CC is between 0 and 1.5-V, the devices SN74LVT16244B are in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5-V, OE should be tied to V _CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
These devices are fully specified for hot-insertion applications using I  and power-up 3-state. The I  circuitry off off disables the outputs, preventing damaging current backflow through the devices when they are powered down.The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.
The SN54LVT16244B is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74LVT16244B is characterized for operation from 40°C to 85°C.
